HUMIDIFIER PAN.

Application fi1ed October 1, 1926. Serial No. 138,942.

This invention relates to humidifying pans for bot-air :Eurnaces and has for its ol ject the provision of a water pan or container of inexpensive construction Which may be easily placed in position in the furnace and will be fir1nly held without the use of bolts or similar fastening devices. Another object of the invention is to provide a pan which Wlll furnish an ample supply of moist vapor to oirculate through the building with the hot air and counteract the effects of dry heat upon the woodwork of the building, the furniture therein, and the health of the occupants. The invention is illustrated in the accompanying drawing and Will be hereinafter fully described, the novel features being particularly pointed out in the appended claims.

In the drawing,

Figure 1 is a vertical section of a, portion of a bot-air furnace showinp; the improved pan in position therein;

Figure 2 is a top plan view of the par. with the adjacent parts of the furnace in horizontal section.

In the drawing, 1 designates a part of the outer Shell or casing of a hot-air :Eurnace, 2 a part of the tire-box, 3 a part of the gratering, and 4 the ash pit.

In carrying out the present invention, an opening 5 is formed through the shell 1 and a rame plate 6 is secured over the end portions of said opening, the opening and tram-e being located immediately over the front 7 of the ash pit. Tlxe front top plate 8 of the ash pit extends from the grate ring 3 to the frame plate 6 and is provided with an upstanding boss 9 having a central opening theretlnrough, the top of the boss seing in a l1orizontal plane somewhat above the horizontal plane of the lower side of the opening through the trame plate 6. 'he water pan 10 is a single integral castinp; having an upstanding ri1n defining straight parallel sides and arcuate back and front portions, the pan being rather shallow and fitting closely but slidably through the frame plate 6 so as to be partl;, supported thereby. The front curvature o the pan harmonizes with the shell oi' the furnace While the curvature of the back of the pan permits it to assume a concentric relation to the fire place and obtain maximum exposure to the heat radiating theretrom. Near the back of the pan, a teat or nipple 11 rises fromthe bottom thereof and the, base et t-his teat or nipple is concave or socketed to fit over and rest firmly upon the boss 9 whereby to a1d in supporting the pan and preventing its displacement.

To increase the stability of the pan on its support, the lower end of the nipple is slightly extended to definc a lug 12 fitting closely within the opening in the top of the boss 9, and the nipple has an attenuated bore or passage 13 extending vertioally therethrough for a purpose which will presently appear.

The pan may be filled by manually pour 111g wat-er through the part thereof projecting beyond the frame plate 6. It is obviously desirable, however, to provide for an automatic replenishment or supply of the water and, in actual practice, a pipe 14:, conneoted with any convenient source of supply, Will be provided to lead the water to the pan, a regulating valve 15 being interposed in the pipe and adjusted to permit the flow of water at the desired rate. Tire outlet 16 of the regulating valve is arranged directly over an opening 17 in a plate or cover 18 which rests on the front end portion of the pan and extends over the same to prevent objects dropping into the pan.

The pan is fitted in place loy coing inserted through the opening in the frame plate 6 and pushed in until it rides over and seats upon the boss 9. The water is then turned on through the supply pipe until the pan is filled to the desired levei, and the regulating valve is adjusted to naaintain that level b v restricting the infiow to a rate about equal to the rate of evaporation. Should the inflow exceed the rate of m aporation, tlxere Will lue. au orerfiow through the passage 13 to the ash pit whereby excess volume oi water will be acconnnoclated and the ashes Will be mostened, the rising of dust froni the ash pit through the furnace and the settling of such dust upon objecte in the furnace roo1n being thereby avoided. be noted, upon reference to Fig. 1 that the top wall of the ash pit is inclined upwardly and outwardly and that the back vva]l 01 the pan is spaced from the lire box so that the heat radiating from the tire box and the 2 grate ring ma v circulate under the pan and evaporation will be efiectually accomplished. Inasmuch the pan is located at the air space between the inner furnace shell and the outer casing, the vapor rising from the It Wlll pan wi1l ming]e at once with the hot air flowing throngh the circnlating fines. The pan may be tilted in the plate 6 snflcient1y to clea1 the boss 9 whereupon it may be drawn forward from the furnace, When nec essary, but it is to be noted that While onIy slight tiIting is needed accidental tilting is practically impossible and the 111g 12 provents displacement unless the pan is tilted.

Having fnHy described 1ny invention vvhat I daim as new and desire to secnre by Letters-Patent, is:

1. In a bot-air furnace, the combinati0n o' an ash-pit having a boss on the upper side of its top wall, and a wate1 pan supported at its front portion by the casing of the fnrnace and a socket in its bottom t0 en gage over and rest npon the boss on the ash pt, the pan being further provided wth an overflow ont1et through the socket and the boss.

2. In a bot-air furnace, the combination of an ashpt, a boss on the top wa1] of ch-e ash pit having a central opening therethrough, a water pan having its front: and portion supported at the front and of the top Wall of the ash pit, :1 socket in the bottom of Une pan t0 engage over the boss and a nipple withn the pan having its 1ower end extended into the s0cket and engaging in the opening in the boss.

In testimony whoroof, I. have signod tbis specification.
